Venture Capital Market Map: How VCs Build One in 6 Steps

A venture capital market map is a structured landscape of the companies in a defined market, grouped into categories, that investors build to understand a sector, find white space, and generate a list of companies to meet. A good one shows the layers of a market (infrastructure, tools, applications), the notable startups and incumbents in each, and signals such as stage and funding.

Definition: A venture capital market map is a structured landscape of companies in a defined market, organized by category or value-chain layer, built by investors to evaluate the opportunity, benchmark competitors, and generate a sourcing pipeline.

Most market maps die as slides. They get admired in a partner meeting and never opened again.

The useful ones are working documents: a thesis turned into a list of names, with a reason to call each one. This guide covers why investors build maps, what good ones look like, one six-step method, an illustrative worked example, and how to put the finished map to work. It pairs with the guide to building an investment thesis.

Why investors build venture capital market maps

Market maps do four jobs inside a fund:

• Thesis development. Mapping a sector forces you to define it, see how value flows through it, and decide where venture-scale outcomes are actually possible.
• Deal sourcing. Every company on the map is a potential meeting. The Gompers, Gornall, Kaplan and Strebulaev survey of 885 institutional venture capitalists at 681 firms reported that VCs spend 22 hours of a 55-hour week on networking and sourcing, and that almost 30 percent of their deals were proactively self-generated rather than referred, according to the summary on the Harvard Law School Forum on Corporate Governance. A map is a common way to organize that self-generated work.
• Competitive diligence. When a pitch arrives, the map shows who else is attacking the same problem and how well funded they are.
• Portfolio conflicts and follow-ons. It shows where existing portfolio companies sit and which adjacent companies could become partners, acquirers or rivals.

We think mapping matters more when capital is concentrated, and right now it is. The 2026 NVCA Yearbook describes 2025 as two markets stacked on top of each other, with AI accounting for 65.4 percent of US deal value in 2025, up from 50.9 percent in 2024. Carta's State of Private Markets report for Q1 2026 shows the resulting price gap: an AI foundation model startup at Series A might be raising at a $300 million median valuation while a non-AI startup at the same stage is at $55 million.

When the money herds, the map tells you where it herded. It also shows you the categories nobody is looking at yet.

What good venture capital market maps look like

Published maps show the range of formats:

• Research-firm landscapes. CB Insights publishes market maps continuously. Recent examples from its archive include a manufacturing robotics map covering 116 companies across 14 markets (June 2026) and an oil and gas value chain map covering 235 companies across 24 markets (March 2026).
• Investor landscapes. FirstMark's Matt Turck has published the MAD (Machine Learning, AI and Data) Landscape since 2012. The 2025 edition, published in October 2025 and the eleventh in the series, cut the logo count to about 1,150 from more than 2,000 the year before to improve legibility. It ran from the data layer up through infrastructure, machine learning and AI, a new agent stack, and applications.
• Firm research hubs. Bessemer Venture Partners publishes roadmaps and memos on its Atlas site that show how the firm frames an emerging category before it invests in one.

What they share: a clear boundary, one primary organizing logic, a flow from infrastructure up to applications, and real editorial choices about what to leave out.

Turck's decision to cut the logo count by nearly half is the lesson worth stealing. A map that includes everything stops being a map. It becomes a phone book.

How to build a venture capital market map in 6 steps

1. Define the market boundary. Write one sentence: "Software that helps mid-market field service companies schedule, dispatch and diagnose repairs." Decide what is in and out before you collect anything.
2. Choose the organizing logic. Common options are value-chain layer, customer segment, workflow step, or business model. It usually helps to pick one primary axis and stay on it.
3. Collect companies. Funding databases, accelerator batch lists, product launch sites, conference exhibitor lists, patent filings, job postings, and conversations with operators. Depth in the categories that matter to your thesis tends to beat breadth everywhere.
4. Tag each company. Category, founding year, headquarters, stage, total raised, last round date, notable investors, and one line on what it actually does. Spreadsheet first; the graphic comes last.
5. Pressure-test with operators. Show the draft to three to five founders or buyers in the space. Ask what is missing and which categories are drawn wrong. In our view, this is the step that separates a map from a search result.
6. Visualize and annotate. Build the one-page graphic, then add your view: which categories are crowded, which are early, where the biggest outcomes sit, and which companies you want to meet.

Keep a living version with a date on it. In a fast category, a map older than six months is close to a historical document.

Illustrative example: from 68 companies to 4 meetings

Say a seed fund maps field service software for mid-market operators. After three weeks it has 68 companies across five categories:

Two things jump out. Diagnostic copilots are the most crowded category at 31 percent of the companies, which usually means competitive rounds and higher prices. Parts and inventory and billing are thin at 13 percent each. That's either white space or a sign that buyers won't pay for a standalone product, and asking five operators is probably the quickest way to find out which.

Then the map becomes a pipeline. Of the 68 companies, 26 (38 percent of the map) are seed stage or earlier. Applying the fund's stage, check size and geography filters leaves 12 companies worth contacting. At a one in three rate of turning outreach into a real conversation, which is the rate this particular fund has observed for warm, researched outreach in its own sector, that is 4 first meetings from one map.

Four qualified first meetings is about a week of top-of-funnel output for a small fund. And it came from research, not from waiting.

How to use the map once it's built

A finished map earns its keep when it drives action:

• Prioritize outreach. One approach is to rank by fit with stage and check size, then contact the top tier with a specific reason drawn from the map itself.
• Investigate the white space. Thin categories are either real gaps or graveyards. Interview buyers before you decide which.
• Benchmark inbound deals. When a founder pitches, compare position, funding and traction against the map rather than against your memory.
• Share it selectively. Many investors publish a simplified version to attract founders and invite corrections, while the internal version keeps rankings and diligence notes.
• Update it after every meeting. Each conversation adds a company, moves one, or kills a category. Over a year the map becomes a record of your own diligence.

This is the difference between hunting and gathering in venture. Gatherers wait for decks to arrive. Hunters go find the company first, and we've argued that hunting is most of the job. A market map is the hunter's field guide.

For how a map fits into a firm's wider pipeline, read the venture capital deal sourcing guide; for the weekly routine an individual investor runs around it, see deal sourcing; and for the funnel those companies enter, deal flow.

"But the best deals come through people, not spreadsheets"

That's a fair objection. Referrals still drive most venture deals: in the Gompers survey, almost 30 percent were self-generated, so the majority came through other people. Warm intros from founders and co-investors carry trust that no spreadsheet can.

But.

A map makes the referral network work better. When you already know a category cold, you recognize the right company the moment someone mentions it, and you ask sharper questions in the first call. Founders notice. The map doesn't replace relationships. It gives you something worth talking about.

Common venture capital market map mistakes

• Mixing axes. Grouping some companies by customer and others by technology tends to produce a picture that's hard to read.
• Logo dumping. Including every company hides your point of view, which is much of what makes the map yours.
• Stale data. Stages and company status change fast, so dating each version helps.
• No annotation. A map without a view is research, not an investment thesis.
• Ignoring incumbents. Large companies and their internal tools often define what a startup is allowed to win.
• Stopping at the picture. A map that doesn't produce outreach is closer to a design project.

Practicing market mapping with a fund behind you

A map built for nobody is an exercise. A map a fund will act on is work. Mapping has that second status in 1752vc's Venture Fellow program, because sourcing is part of the eight weeks of live virtual sessions and the companies a Fellow surfaces can end up in the pipeline. About half of 1752vc's deal flow is sourced by Fellows, who earn payouts on the deals that get done. The same weeks cover case studies, real pitch materials and diligence on live companies, so the map has somewhere to lead.

The bottom line

A good market map is narrow, dated, opinionated and tested with people who work in the market. Most of all, it ends in a short list of companies you plan to call this week.

A map you only look at is decoration. A map you call from is a pipeline.

Key takeaways

• A venture capital market map organizes the companies in a defined market into categories so investors can evaluate the opportunity and generate a sourcing list.
• Maps serve four jobs: thesis development, deal sourcing, competitive diligence, and portfolio conflict checks.
• In our view, strong maps have one boundary, one primary organizing axis, and clear editorial choices about what to leave out. FirstMark cut its 2025 MAD Landscape to about 1,150 logos from more than 2,000 for exactly that reason.
• A practical sequence: build the data in a spreadsheet, test it with operators, then visualize and annotate it with your own view.
• We think of a map as finished when it produces outreach: in the illustrative example, 68 mapped companies become 26 at the right stage, 12 worth contacting, and about 4 first meetings.

Frequently asked questions

What is a market map in venture capital?

It is a landscape of the companies in a specific market, grouped into categories such as value-chain layers, workflow steps or customer segments. Investors use it to understand a sector, identify gaps, benchmark competitors against inbound pitches, and build a prioritized list of startups to meet.

How do you build a venture capital market map?

One method: define the market boundary in one sentence, choose a single organizing axis, collect companies from funding databases and operator conversations, tag each with stage and funding data, pressure-test the draft with three to five operators, then visualize it and annotate it with your investment view.

What tools do VCs use to build market maps?

Most start in a spreadsheet and design the visual afterwards in slide or design software. The underlying data comes from funding databases, research platforms such as CB Insights, accelerator batch lists, product launch sites, and direct conversations with founders and buyers in the category.

How many companies should a market map include?

Enough to represent the market without becoming unreadable. Recent CB Insights maps in its archive vary widely in size, with the largest covering more than 400 companies, and FirstMark cut its 2025 MAD Landscape to about 1,150 logos from more than 2,000 specifically to make it legible. For an internal sourcing map, 50 to 100 is often plenty.

How long does it take to build a market map?

A focused internal map of a narrow category often takes a few weeks of part-time work: roughly a week to define the boundary and collect companies, a week to tag and clean the data, and a week of operator conversations before you draw anything. Published industry landscapes take considerably longer.
